Abstract

The invention concerns a method of producing a pulley for a multiple V-belt drive. A blank in the form of a disc (3) with a central hub and a thick rim is first produced. A shallow groove is formed in the rim by rotating the blank and pressing a contoured roller radially against the rim so that the two flanges (4, 4a) are formed. The blank is subjected to a second forming operation which produces a rim with raised edges and a flat central region. A third operation increase the radial height of the flanges and a fourth operation produces the V grooves (5). USE - V-belt pulleys.

Description

Die Erfindung bezieht sich auf eine Vorrichtung ge­ mäß dem Oberbegriff des Patentanspruches.The invention relates to a device ge according to the preamble of the claim.

In der DE-PS 38 06 024 wird die gattungsbildende Vorrichtung beschrieben. Die Stauchrolle weist an ihrer Arbeitsseite, d. h. ihrem Umfang, eine Stauchnut auf, die die Umfangsseite der zu bear­ beitenden Ronde wulstig verformt. Diese Wulst wird dann anschließend durch weitere Stauchrollen so bearbeitet, daß die zylindrische Auflagefläche ge­ schaffen wird, in der die letzte Stauchrolle die Nuten der Poly-V-Scheibe einpreßt.In DE-PS 38 06 024 the generic Device described. The squeeze roller instructs their work side, d. H. their scope, a On the circumferential side of the bear the round disc is bulged. This bead will then then by further upsetting rolls like this edited that the cylindrical bearing surface ge will create in which the last upset roll Grooves in the poly-V washer.

Die gattungsbil­ dende Einrichtung hat sich bereits in der Praxis ausgezeichnet bewährt, und der Erfindung liegt die Aufgabe zugrunde, die erste Stauchrolle so auszubil­ den, daß ein besserer Materialfluß im Randbereich der zu bearbeitenden Ronde erzielt wird, so daß ein schnelleres Bearbeitungsverfahren möglich ist.The generic bil The facility has already been put into practice proven excellent, and the invention lies Based on the task of training the first compression roll in this way that a better material flow in the edge area the blank to be machined is achieved so that a faster machining process is possible.

Diese der Erfindung zugrundeliegende Aufgabe wird dadurch gelöst, daß zwei teilkreisförmige Stauch­ nuten auf dem Umfang der ersten Stauchrolle vorge­ sehen sind, so daß in der Ronde bei Einsatz der ersten Stauchrolle zwei nach außen gebogene Flügel erzeugt werden.This object underlying the invention will solved in that two part-circular upsetting grooves on the circumference of the first compression roller are seen, so that when using the first upsetting roll two outwardly curved wings be generated.

Durch diese Anordnung wird bewirkt, daß das Material in der Ronde besser fließt und daher weniger ver­ härtet. Aus diesem Grund kann mit der nachfolgenden Stauchrolle wesentlich schneller gefahren, d. h. ge­ arbeitet werden.This arrangement causes the material flows better in the round blank and therefore less ver  hardens. For this reason, the following can Squeeze roller moved much faster, d. H. ge be working.

Außerdem hat diese erfindungsgemäße Anordnung wei­ terhin den Vorteil, daß aufgrund der geringeren Ver­ härtung des Materials die nachfolgenden Bearbei­ tungsrollen erheblich geschont werden.In addition, this arrangement according to the invention has white terhin the advantage that due to the lower Ver hardening of the material the following processing tion rollers are considerably protected.

Ein Ausführungsbeispiel der Erfindung wird nach­ folgend anhand der Zeichnung erläutert. Die Zeich­ nung zeigt dabei inAn embodiment of the invention will follow explained below with reference to the drawing. The drawing nation shows in

Fig. 1 bis 4 verschiedene Stadien des Arbeitsverfah­ rens. Fig. 1 to 4 different stages of the Arbeitsverfah ren.

In der Zeichnung ist eine Stauchrolle 1 gezeigt, an deren Umfang zwei teilkreisförmig ausgebildete Stauchnuten 6 und 6a vorgesehen sind.In the drawing, a compression roller 1 is shown, on the circumference of which two compression grooves 6 and 6 a, which are of part-circular design, are provided.

An einer Ronde 3 werden an ihrem Umfang bei Einsatz dieser Stauchrolle 1 zwei gewölbte, nach außen ge­ richtete flügelartige Teile 4 und 4a erzielt.This compression roller 1 at its periphery two arched in use on a round plate 3, achieved outwardly ge directed wing-like parts 4 and 4a.

In den weiteren Darstellungen, d. h. in den Fig. 2 bis 4 der Zeichnung, ist nun die weitere Verformung der Ronde 3 dargestellt, und in Fig. 4 ist erkenn­ bar, daß durch die Poly-V-Stauchrolle 1c nunmehr die Einkerbung in die zylindrische Auflagefläche 5 ein­ gepreßt werden, wobei - wie dies die Zeichnung deut­ lich zeigt - fluchtend mit der Ebene der Ronde 3 nunmehr auch im mittleren Teil der zylindrischen Auflagefläche 5 eine Erhebung geschaffen werden kann.In the further representations, that is, in FIGS. 2 to 4 of the drawing, the further deformation of the round blank 3 is now shown, and in FIG. 4 it can be seen that the poly-V compression roller 1 c now causes the notch in the cylindrical bearing surface 5 are pressed, whereby - as shown in the drawing clearly Lich - aligned with the plane of the circular blank 3 now an elevation can be created in the central part of the cylindrical bearing surface 5 .
